Title: ADAPTATION TO POLYETHYLENE STRESS MAINTAINS TOTIPOTENCY OF CELL LINES OF ORYZA SATIVA L. CV. SWAT-1 FOR A LONGER PERIOD Authors: HUSSAIN SHAH, AZHAR; HUSSAIN SHAH, SAFDAR; AHMAD, HABIB; AHMAD SWATI, ZAHOOR; MUHAMMAD ABBASI, FIDA; FARHATULLAH, FARHATULLAH; HUSSAIN SHAH, ABRAR Abstract: Cell suspension cultures of rice cv Swat-1 were adapted to osmotic (polyethylene glycol, PEG) and ionic (lithium chloride) stresses to find components of stress having greater inhibitory effects on regeneration frequency of cells. In early stage suspension were in cell aggregates or in micro calli form and regeneration frequency of one month old suspensions was about 74%. One month old cultures were incrementally adapted to 20% PEG and 20 mM LiCl. After 50 repeated batch cultures the size of cell aggregates of control and LiCl adapted cell lines turned into fine suspensions, while the suspension of PEG adapted lines remained in small clusters with whitish pale coloration. The relative growth rates of adapted and unadapted cell lines were similar at respective media but the regeneration potential of unadapted and LiCl adapted lines dropped to 30% and 10 %, respectively. In contrast regeneration frequency of PEG adapted line increased to 80% with early recovery of plantlets. These data reveal that regeneration capacity of cell cultures decreases with age of cultures and with ionic stress, while osmotic stress not only maintain but enhance regeneration frequency of cell cultures over a longer time.

Title: SEASONAL AND CULTIVAR EFFECTS ON NODULATION POTENTIAL OF SOYBEANS Authors: MUHAMMAD, ASIM; KHAN KHALIL, SHAD; ZAMAN KHAN, AMIR; MEHMOOD WAZIR, SULTAN Abstract: Indigenous land races of soybean (Glycine max (L.) Merrill) have great potential for seed quality and grain yield. However information on its nodulation potential are limited. The objective of the present study was to explore its nodulation potential in comparison with improved varieties. Three indigenous land races, viz., Kulat brown, Kulat white and Mothi and two improved varieties (NARC-II, Swat-84) of soybean were planted at monthly interval from April to July in 2004 and 2005 growing season at K.P.K Agricultural University, Peshawar, Pakistan. The number and fresh biomass weight of nodules plant-1 was determined. The two years average of nodules plant-1was significantly affected by years, planting dates, varieties and planting dates x varieties interaction. Maximum nodules number (24.3 plant-1) was recorded for May planted crop. The smallest number of nodules (7 plant-1) were produced by April planted crop. Kulat brown produced maximum nodules (18.4 plant-1). Land races produced greater number of nodules than improved varieties. Nodules plant-1decreased when planting was delayed from May to July. Maximum nodules weight (53.2 mg plant-1) was recorded for May planted crop. Years, varieties and planting dates x varieties interaction did not affect nodules weight plant-1. Land races exhibited greater nodulation potential than improved varieties.

Title: CORRELATION AND PATH ANALYSIS OF GRAIN YIELD AND YIELD COMPONENTS OF SOME TURKISH OAT GENOTYPES Authors: DUMLUPINAR, ZİYA; KARA, RUKİYE; DOKUYUCU, TEVRİCAN; AKKAYA, YDIN Abstract: This research was carried out in 2002-03 and 2005-06 crop years in Kahramanmaras province located in EastMediterranean Region of Turkey. The experimental design was randomized complete block design with four replications. The aim of research was to determine correlation coefficients of 17 oat genotypes among grain yield (GY) and plant height (PH), grain number panicle-1 (GNP), grain weight panicle-1 (GWP), 1000 grain weight (1000-GW), grain filling period (GFP), days to maturity (DM), panicle number m-2 (PN m-2). Determined direct and indirect effects of yield components on GY through path analysis were also determined. Based on results of correlation coefficients, GY was significantly but negatively correlated with PH (r = -.280*), while the other yield components were not significantly related with GY. Path coefficient analysis indicated that PN m-2 (0.23), 1000-GW (0.35), GNP (0.22), GFP (0.16) and DM (0.09) had positive direct effects on GY while GWP (-0.40) and PH (-0.24) had negative direct effects on GY. However, when the positive direct and indirect effects were added to the negative direct and indirect effects for traits, the sum of direct and indirect effects of GFP (72.48), PN m-2 (57.34) and DM (35.05%) on GY were positive. The effects of these traits were higher than those of 1000-GW and GNP. The sum direct and indirect effects of PH was negative and at the rate of 58.92%. Therefore, GFP, PN m-2, DM and PH could have priorities in breeding programs for the conditions of East Mediterranean region of Turkey.

Title: PHOTOSYNTHETIC CHARACTERISTIC OF AN ENDANGERED SPECIES CAMELLIA NITIDISSIMA AND ITS CONSERVATION IMPLICATIONS Authors: XUE QI, XIAO; JIANG, YUN-SHENG; WEI, XIAO; TANG, HUI; XIONG, ZHONG-CHEN; YE, WAN-HUI; WANG, ZHANG-MING Abstract: Camellia nitidissima is a shrub and a famous ornamental species with golden-yellow flowers. The responses of net photosynthetic rate (Pn) to the incident intensity (PFD) and the diurnal course of variation in major physiological and environmental variables of young and mature C. nitidissima were studied with LI-6400 (Li-Cor Inc., USA) portable photosynthesis system. The results showed that the leaves of C. nitidissima had the highest photosynthetic ability in autumn, the middle level of photosynthesis in summer and spring, and a relatively lower level of photosynthesis in winter. Mature plants of C. nitidissima had both relatively high the maximum net photosynthesis rate (Pmax) and light saturation point (LSP), indicating a good adaptability to both strong and weak lights; young plants of C. nitidissima had both relatively low Pmax and LSP, indicating a good adaptability to weak light, but a depression under strong light. C. nitidissima is a shade loving plant and should be planted in shade habitat. Some suggestions for the management of the species are proposed
